Application filed March 28, 1908. Serial No. 423,950.

To all tvhom it mag concern:

Be it known that I, WILLIAM J. BURRows, a citizen of the United States of America,

residing at Plymouth, in the county of- VVayneand State of Michigan, have invented certain new and useful Improvements in Air-Guns, of which the following is a specifalse and true barrels as will be hereinafter set forth, and consists in the novel arrangement and comblnatlon of the various parts and in certain details of construction, as

- will be hereinafter described.

In the drawings illustrating my invention,-Figure 1 is a vertical central section through the false barrel, showing the inner or true barrel partly in elevation; Fig. 2 is a sectional view showing the parts ina different position from that shown in Fig.1,

Figs. 3 and 4 are sectional perspective views illustrating the retaining means for-the inner or true barrel Fig. 5 is a detached perspective view of the forward sight; and Fig. 6 is a sectional perspective view of the-inner end of the true barrel,

In the drawings thus briefly described, A represents the false barrel of any approved construction, B is the piston working therein, and O the usual projectile startlng rod carried by the piston.

O is the apertured piston abutment'secured within the false barrel, and D the true barrel removably mounted within the false and carrying the usual closure cap E'at its outer end.

The false barrel at its outer end is formed with the ,usual load opening F through which the projectiles are inserted within the magazine, and G is a forward sight projecting upwardly'through a slot H in the false barrel and secured to the latter, as will be more fully hereinafter set forth.

In order that the starting rod may properly reciprocate withinthe true barrel during the use of the gun, it is necessary that the barrcl should accuratelyaline with the opening or aperture in the piston abutment. It has been the practice heretofore to support the inner end of the true barrel in registration with the abutment opening usually by securing the barrelend within said opening.

-This has been objectionable, however, on 5 account of the time and accuracy necessarily required in assembling the parts. To ob'- viate this, I provide means for support ng the inner end of the true barrel in operative relation to the abutment opening of a novel character, and which further serve to guide the inner end of'the barrel so'that as the same is inserted within the false it will automatically find its proper position in relat on to the abutment opening, thus permittlng the parts-to be properly and effectively assembled in a minimum space oftime.

I have here shown the support preferably in the form of a disk, as I, carried preferably upon the extreme inner end of the-true barrel and of such diameter that when the true barrel is in place it will be in proper position to receive the starting rod. As will be ob vious, the disk serves, in addition to a support, as a guide, and carrier during the msertion of the barrel the inner end of the latter to its proper seat.

In order to lessen the requirement for.ex-

treme accuracy of construction of the parts to obtain the necessary alinement between the true barrel and the abutment opening, the support may be of somewhat less diameter than the internal diameter of the false barrel, so that in the normal position of the parts the inner end of the true barrel while in operative relation to the abutment opening maybe more or less out of exact alinement therewith, as indicated in Fig. 2. To overcome this inaccuracy of construction, the outer or free end of the starting rod is tapered, as at J, so that during the operation of firing it will act automatically as it enters the true barrel to bring the same into exact alinement with the abutment opening in the manner shown in Fig. 1.

Where the support for the true barrel is independent of the abutment, I provide locking means at the outer ehd of the true barrel her K carried by the true barrel at its outer end near the cap E, which is adapted to have a locking engagement, effected by a relative rotary movement of the false and true barrels, with a retaining member L which holds the forward sight in place. More particularly, the locking member described is in the form of a yoke-shaped plate, which is rigidly attached to a collar M upon the true barrel. The retaining means for the forward sight is in the form of a plate 0 formed preferably integral with the sight, and adapted to be rigidly attached to the interior of the false barrel after the sight proper G has been inserted upwardly through the opening in the barrel end. This retaining plate for the sight is provided with a slot or opening P, which as shown is brought opposite the load opening F and registers therewith, the opening (as indicated in Fig. 4:) extending upwardly in the plate-O to the junction line with the sight proper.

The true barrel is inserted within the false with the locking member K to one side of the retaining plate, and the parts are so proportioned that when the true barrel reaches its innermost position within the false the member K will be opposite the slotor opening P. Upon rotary movement of the inner barrel, the lock is brought into engagement with the slot in the retaining plate, thereby locking the parts against relative endwise movement, and at the same time the lock serves to close the load opening F the member K serving the double function of a lock and a closure as indicated. The inner end of the true barrel may be provided if desired with wings or guide flanges a and b, which serve to conduct the projectiles in the magazine to the opening 0, through which they pass into the true barrel.

It will be understood that while I have shown a disk as the preferred form of support for the inner end of the true barrel, other supporting means may as well be employed, and I do not desire to be limited to the particular form shown, although I deem the same preferable in use on account of its simplicity of construction.

What I claim as my invention is, I

1. In an air gun, the combination with the false barrel provided with an apertured piston abutment, of a removable true barrel held against outward movement within the false barrel, and means independent of the abutment for supporting the inner end of the true barrel in operative relation to the abutment opening.

2. In an air gun, the combination with the false barrel provided with an apertured piston abutment, of the true barrel removably mounted within the false barrel, and means carried by the true barrel acting on assemblage of the parts to support the inner end of said barrel in operative relation to the abutment opening.

3. In an air gun, the combination withthe false barrel provided with an apertured piston abutment, of the true barrel removably mounted within the false barrel and terminating at the abutment, and a disk member upon the inner end of the true barrel serving to support the latter in operative relation to the abutment opening.

4;. In an air gun, the combination with the false barrel provided with an apertured piston abutment, of the true barrel removably mounted within the false barrel with its inner end partially out of alinement with the abutment opening, and means for automatically alining the true barrel with the abutment opening during the operation of shooting.

5. In anair gun, the combination with the false barrel, of the piston working therein, an apertured piston abutment, the true barrel removably mounted within the false barrel, with its inner end supported independently of the abutment in partial registration with the opening, and a projectile starting rod carried by the piston adapted during the operation of shooting to guide the true barrel into alinement with the abutment opening.

6. In an air gun, the combination with the false barrel, of the piston working therein, an apertured piston abutment, the true barrel removably mounted within the false barrel, a support for and carried by the inner end of the true barrel holding the latter in partial registration with the abutment opening, anda projectile starting rod carried by the piston and having a tapered outer end, for the purpose set forth.

7. In an air gun, the combination with the false barrel, provided interiorly with an apertured piston abutment, of the true barrel removably mounted within the false barrel and terminating at the abutment, means for supporting the inner end of the true barrel independently of the abutment and in operative relation to the abutment opening, and a lock at the outer end of the true barrel for holding its opposite end against the abutment.

8. In an air gun, the combination with a false barrel having a load opening in its forward end, of the forward sight, a retaining member for the sight secured to the interior of the barrel near the load opening therein, the true barrel, and a locking member for the true barrel adapted upon relative movement of the barrels to engage the sightretaining member and close the load opening.

9. In an air gun, the combination with a false barrel having a load opening formed in its forward end, of the forward sight, a slotted retaining plate for the sight upon the interior of the false barrel arranged with terminating at the abutment, and a com- 10 its slot opposite the load opening, and a bined support and guide for the inner end lockin member carried by the false barrel of the true barrel.
